CLEANING AND POLISHING COMPOUND.

No Drawing.

To all whom it may concern:

Bt it known that I, EMIL M. SMITH, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and 5 State of Wisconsin, have invented certain new and useful Improvements in Cleaning and Polishing Compounds; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to a cleaning and polishing compound.

Objects of this invention are to provide a cleaning and polishing compound which is particularly adapted for use on metals, which is very effective and will clean and polish the metal in a very short time and with a minimum of effort, which will not injure the hands of the operator, which may be cheaply and readily produced, and which has lasting qualities.

This compound is formed by mixing four ounces of oxalic acid, and four ounces of rotten stone, powdering and grinding these ingredients thoroughly so as to secure a thorough mixing thereof. Thereafter, two

ounces of ammonia are added and one gallon of temperate water of about 70 to 73 degrees F. This mixture is thoroughly agitated and is allowed to stand with occasional agitation for about twelve hours before using. Thereafter, it may be bottled and put away for future use. The oxalic acid has a decided bleaching effect and aids in the removal of stains. The ammonia 85 aids in securing proper solution, also takes up grease and other coatings of this general type, and the rotten stone acts as amechanical agent for loosening any minute film that Application filed August 25, 1923.

desired polish.

It has also been found that this polish does not injure the operators hands and also has the desirable characteristic of not deteriorating with age.

It is to'be distinctly understood that the exact portions of this compound may be varied without departing from the'spirit of the invention. I have, however, given the proportions, which I find from practical experience, worked with the greatest efficiency.

I claim:

1. A polishing compound formed by the mixture of oxalic acid, rotten stone, am-

monia and water.

2. A polishing compound formed by the mixture of the following ingredients in approximately the following proportions: four ounces oxalic acid, four ounces rotten stone, two ounces ammonia and one gallon of temperate water.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of l Visconsin.

EMIL, M. SMITH.
